An AQI between 201 and 300 is considered to be poor.

Kuldeep Srivastava, the head of India Meteorological Department’s (IMD) regional weather forecasting centre, said that the wind speed was negligible through the night on Wednesday, which would result in Delhi’s AQI to toggle between poor and very poor categories the following day.

“The winds, which were calm through the night, did not allow dispersion of pollution particles in the national capital,” he added.
